Activity measurement of the Fe-Zn binary system was carried out by employing an isopiestic method at 1100 and 1200 K to determine the activities of components in the Zn-Fe-S ternary system. The activities of the components were calculated by applying the Gibbs-Duhem equations to the phase relation of metal-sulfide equilibrium. Results showed that in the α-solid solution of the Fe-Zn alloy, both the activities of Fe and Zn exhibited considerable positive deviations from Raoult's law. Relation between the equilibrium S partial pressure and the composition of the condensed phase was determined. The activity of FeS in the pyrrhotite can be regarded as almost unity.
